Probability is the ratio of: the number of observations of an event n(A) compared to the total number of observation n(S). Generally it could be written as
P(A) =
Use combination to solve this problemThe event being observed n(A) in this problem is 2 engineers being selected from 4 engineers. The observation n(S) is about 2 people being selected from 10 people (engineers + pilots).
n(A) could be determined using combination of 2 engineers from 4 engineers
n(A) =
n(A) =
n(A) =
n(A) =
n(A) =
n(A) = 6
n(S) could be determined using combination of 2 people from 10 people
n(S) =
n(S) =
n(S) =
n(S) =
n(S) =
n(S) =
n(S) = 45
The probability
P(A) =
P(A) =
P(A) =
The probability is 2/15
3 hours and 45 mins is 3.75 hous
speed = 240/3.75
= 64 miles/hour

C=p+R x p
C=30.99 + .05 x 30.99
Order of operations states do the multiplication first
C=30.99 + 1.55
C=32.54
